Editorial Reviews

"Those CATegorical felines are back. This time they turn their attention to the characteristics of mammals, reptiles, amphibians, birds, insects, and fish. The energetic rhyming text and zany cartoon illustrations will captivate students and make it fun to learn about what makes each group distinctive. Goneau's cartoon creatures nicely complement the facts that Cleary imparts in his rhythmic narrative, and in several cases, labels are included in the illustrations to reinforce a point. Each volume concludes with two pages summarizing the key characteristics of the animal class under discussion. Solid additions to the series." --School Library Journal, Series Made Simple


"The Categorical cats are back again, ready to explore animal classification in Brian P. Cleary's new series. Brief, but interesting discussion follows, moving the reader from page to page until they are asked to recall what they have learned. Brightly colored cartoons provide comic relief as they extend the story. An endnote indicates a website for additional activities and games. The presentation is so much fun that readers are unaware of how much they are actually learning as they study traits animals have in common and come to the understanding that they are classified because of these traits."—Library Media Connection
